What do you have in menu.xhtml. If it should never be displayed, you can add a redirect meta tag to forward the user to another page. Other option is to define a page action in pages.xml where you retun a navigation rule to displayOverview.xhtml.
Thanks for the reply. I actually tried using pages.xml, but I wasn't able to get this to work. Can you give me a snippet of code of the redirect that I can use in menu.xhtml. Thanks!
